The fan motor on my air compressor is broken. I have been told my air compressor is an air conditioning unit by the last repair man who looked at it, and he assured me I wouldn't need it until I needed the air conditioner. However, the air compressor keeps trying to turn on when the heat comes on. Called him and he assured me I don't have a heat pump and it should not be turning on. But if it shouldn't be turning on, why is it trying to?
